When we’re born again, we are no longer of the flesh nor in the flesh, and life is by the Spirit. That means our primary awareness becomes God—with us and in us—and not our previous fascination with how to be or what to do in our days. Life navigation used to be outward oriented; now it is inward. Our greatest prize and joy becomes knowing God—even when we’re with people—and trusting Him to produce in us and through us what He wants and would be to the people and situations around us.
Really, most of us are used to dressing up our behaviors and interactions with people. The flesh sends us the message that we should enhance it all, which will give us better odds of getting what we want. And it might, actually, so that can become our goal in life. Control yourself = Get what you want. In fact, if you do not enhance your interactions with people in the ways that others do and expect, they might view you as different or odd. Not with the program. But you’ll know better.
In addition, Christian authenticity does not simply mean honesty, which can be brutal and harsh. Christian authenticity is living in and trusting in our union with Christ, who manifests whatever fruit He wants for a given situation. Life by the Spirit for us means love from God and love for others. If we're "cracking the whip" on people or "just being honest," that's not Spirit-led, that's fleshly.
